This document contains an interactive PowerPoint presentation about the major human body systems: respiratory, circulatory, digestive, muscular, and skeletal. Each system section provides 3-4 "gross and cool facts" about that system, such as how long the intestines are, how many miles of blood vessels are in the body, how many bones are in the hand, and comparisons of bone structures between humans and other animals. The presentation aims to educate viewers about interesting anatomical details of each major body system through fun facts.

8. Digestive System
Gross and Cool Facts!
• HOW LONG ARE YOUR INTESTINES? At least 25 feet in
an adult. Be glad you're not a full-grown horse -- their
coiled-up intestines are 89 feet long!
• Chewing food takes from 5-30 seconds
• Swallowing takes about 10 seconds
• Food sloshing in the stomach can last 3-4 hours
• It takes 3 hours for food to move through the intestine
• Food drying up and hanging out in the large intestine can
last 18 hours to 2 days!
• Americans eat about 700 million pounds of peanut butter.
• Americans eat over 2 billion pounds of chocolate a year.
• In your lifetime, your digestive system may handle about 50
tons!!

9. Respiratory System
Gross and Cool Facts!
• Your lungs contain almost 1500 miles of airways
and over 300 million alveoli.
• Every minute you breathe in 13 pints of air.
• Plants are our partners in breathing. We breathe
in air, use the oxygen in it, and release carbon
dioxide. Plants take in carbon dioxide and
release oxygen. Thank goodness!
• People tend to get more colds in the winter
because we're indoors more often and in close
proximity to other people. When people sneeze,
cough and even breathe -- germs go flying!

10. Circulatory System
Gross and Cool Facts!
• The body of an adult contains over 60,000 miles
of blood vessels!
• An adult's heart pumps nearly 4000 gallons of
blood each day!
• Your heart beats some 30 million times a year!
• The average three-year-old has two pints of
blood in their body; the average adult at least
five times more!
• A "heartbeat" is really the sound of the valves in
the heart closing as they push blood through its
chambers.

11. Muscular System
Gross and Cool Facts!
• You have over 30 facial muscles which
create looks like surprise, happiness,
sadness, and frowning.
• Eye muscles are the busiest muscles in
the body. Scientists estimate they may
move more than 100,000 times a day!
• The largest muscle in the body is the
gluteus maximus muscle in the buttocks.

12. Skeletal System
Gross and Cool Facts!
• The human hand has 27 bones; your face has
14!
• The longest bone in your body? Your thigh bone,
the femur -- it's about 1/4 of your height. The
smallest is the stirrup bone in the ear which can
measure 1/10 of an inch.
• Did you know that humans and giraffes have the
same number of bones in their necks? Giraffe
neck vertebrae are just much, much longer!
• You have over 230 moveable and semi-
moveable joints in your body.
